    (54) Video signal digital recording/reproducing apparatus


    (57) In a video signal recording/reproducing apparatus, a video signal is subjected to bit rate reduction including a variable length processing to obtain a coded data. The coded data is separated into a basic data which shows a basic construction of video image and is given by a fixed data length and an additional data which shows detailed information of the video image and is given by a variable data length. In recording the coded data containing these basic data and additional data on a recording medium, only the basic data are gathered and recorded in a continued region on the recording medium and only the additional data are gathered and recorded continuously in a region other than the basic data recording region, by which both data are recorded in separated regions on the recording medium.
